BAND AND TIRE SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 444,547, dated January13, 1891.

Application filed March 28, 1890. Serial No, 345,789 (No model.)

To all whom it may concern:

Be it known that I, JONATHAN H. SAMUELS, a citizen of the United States,residing at Moline, in the county of Rock Island and State of Illinois,have invented certain new and useful Improvements in Hydrostatic Bandand Tire Setters for Vagon-Wheels and other Purposes, of which thefollowing is a specification, reference being had therein to theaccompanying drawings, making part of this specification.

The present invention has for its object to provide a band and-tiresetting machine operated by hydrostatic pressure against a verticalpiston, by which a series of pivoted clamps or encircling sections aremade to converge or approach each other in consequence of being forcedlongitudinally within the interior ofa frustum of a cone.

Figure 1 is a vertical section of my improved band and tire settingmachine in complete working order setting one of the middle bands on awagon-hub. Fig. 2 is a top view of the same parts, except that thehuband center standard are omitted. Fig. 3 is a section of the machine notin operation with the piston down to the lower end of its stroke and theclamps or encircling sections thrown together to receive the band andthe hub on which the band is to beset. Fig. at is a section of theoperating part-s shown in Fig. 1 in the act of setting one of the endbands on a hub, a few of the minor details being omitted. Fig. 5 is aninterior view of one of the series of pivoted clamps or encirclingsections as viewed from the center standard. Fig. 6

. is a section, and Fig. 7 a view, of the under side of the annularpacking-ring a on an enlarged scale and having a coil-spring u embeddedin its fold.

A represents the hub of the wheel on which the. bands are to be set.

B is preferably a frustum of a hollow cone or zone of a sphere.

O is a hydrostatic piston; D, the cylinder surrounding it; E, thebase-plate.

F F F F are four vertical standards supporting the part B.

his one of the pivoted converging clamps.

dis a slotted bracket, to which the lower ends of the clamps arepivoted, and is bolted to the upper end of the piston.

j andj are removable steel dies that encircle the band which is beingsetupon a hub, and are adapted to fit and be fastened in a seat providedfor them in the upper ends of the clamps 71, where they are held by thecountersunk bolts 7t.

Z is a center standard passing upward" in the center of the hub, and ismade firm to the upper end of the piston C, and having a screwthread outupon it.

m is an adjustable plate made to be raised and lowered by means ofathread cut through it, so that it can be turned up or down upon thecenter standard Z to any height necessary to accommodate the differentlengths of hubs, and is then made fast by the lock-nut n, Fig. 3.

0 is one of the middle bands of the hub being operated upon, as shown inFig. 1; r, the end band being set, as shown in Fig. 4.

s is the inlet to the cylinderD, and through which the water or otherfluid is to be forced for operating the piston O.

u is an annular packing-ring seated in a groove formed by thepacking-ring t and the upper end of the cylinder, as shown.

a is an annular coil-spring embedded in the packing-ring a. Theclamp-brackets '6 are each secured to the top of the piston by thecap-screws c and o, as shown in Fig. 1, or may be secured thereto by anyother suitable means, or they may, if desirable, be cast integral withthe piston itself.

A simple metallic ring cl, Fig. 4, encircling the center screw-standardZ, serves as a hitching device for one end of the coil draw-springs f,which act between said ring and the pivoted clamps to draw them inwardlyuntil their upper ends impinge against each other and form a continuouscircle. The object of these coil-springs is to keep the upper ends ofthe pivoted clamps drawn inwardly as far as they can move, so that aniron band which it is proposed to set upon a hub or rim ofa wheel may beforced down into its seat, as

shown in Figs. 1. and 4:, the rounded upper ends of the clamps causingthe pivoted clamps to yield outwardly as the band or tire is presseddown between them, the elastic bearings holding it in position duringthe process of upsetting it to fit the hub or rim of the wheel.

The object of the toilspring u is to constan'tly crowd the flanges ofthe packing-ring l the tires on the rims of said wheels.

the packing-ring, consequent upon the first rush of water into thecylinder, is by this coilspring checked or stayed until the fullpressure of water is-exerted upon the hollow of the packing-ring.

No force pumping apparatus is shown in the drawings, as almost any ofthe usual make of force-pumps can be used, there being no peculiarity ofpump required with this mal chine. used.

Instead of employing a frustum of a cone, as described in the drawings,a zone of a sphere may be used or any other form that will not interferewith the general functions sought to be accomplished.

Having now sufiiciently illustrated the mechanical features of my saidimproved hand and tire setting machine, its operation is as follows: Thepiston (J being down to the lowermost end of the stroke, as shown inFig. 3 of the drawings, and the pivoted clamps 7t 71, &c., beingslightly drawn inwardly at the top ends, so as not to touch thesurrounding inclined surface of the hollow cone I the band is then to beforced down into its seat in the'jaws of the clamps, the latter yieldingoutwardly to receive it. The hub is then to be dropped down over thecenter standard and rest upon the adjustable plate m. Now the force-pumpis set in operation, forcing the water or other fluid into the cylinderthrough the inlet 5, and the raising of the piston causes the upper endsof the clamps h h 71, &c., to draw inwardly by the converging form ofthe hollow cone-shaped rim B, thus upsetting or shortening the band tothe required size to bind the hub as tightly as desired. As soon as theband is properly set. the force-pump is made to cease working and thewater or other fluid, as the case may be, is allowed to escape out ofthe cylinder through any ordinary stop-valve into a cistern below, thepiston having settled down into the cylinder, as before. The hub, withthe It preferred, stored pressure can be band properly set, may now beremoved and the machine put in readiness to receive another band andhub.

Although the machine as represented in the drawings is seemingly fittedto set bands 011 hubs only on wheels of vehicles, still it is evidentthat by enlarging the diameter of the machine the same would be equallyapplicable, and it is my desire to use it for setting In order toaccommodate the same machine to setting bands of different sizes withincertain limits, I have provided the pivoted clamps h h, 850., withremovable steel dies or jaws of different thicknesses, as shown atj,Fig. 1, and j, Fig. l, the purpose being to extend inwardly a littlefarther or not so far, as the case may be, to accommodate differentdiameters of bands. In the drawings I have shown and illustrated six ofthese pivoted clamps h; but, inasmuch as the same result may besubstantially accomplished with some other number, I do not wish to belimited by that exact number. I have chosen. that number merely frompreference.

It will be seen that by myplan of construction the middle bands may beset upon a hub so as to be a little smaller of diameter on the side nextto the spokes, thereby offering additional resistance against theircoming off when the hub has become thoroughly seasoned and shrunken, andin like manner also the end bands on the hub can be slightly contractedon the inner side of the band as a further security against slippingoff.

I claim- 1. In a band'and tire setting machine, the combination of aseries of pivoted clamps h 72 7a, consisting of two or more such clamps,the hydrostatic piston O, and the converging or cone-shaped ring B,substantially as and for the purpose set forth.

2. In a band and tire setting machine, the combination of the piston 0,center standard Z, and pivoted clamps h h 71, substantially as and forthe purpose set forth.

3. In a band and tire setting machine, the combination of the centerstandard I, adj ust able plate at, lock-nut 'n, pivoted clamps h h h,and movable dies j, substantially as described.

4-. In a band and tire setting machine, the combination of thepull-springs f, annular ring (Z, and pivoted clamps 71 as and for thepurposes set forth.

5. In a band and tire setting machine, the combination of the annularpacking-ring 'u, and the inclosed coil-spring to, as and for thepurposes set forth.
